摘要
针对ADAS的特点和测试问题,为提高测试效率,尽早发现问题,本文利用虚拟现实和实时仿真技术,基于NIPXI平台建立车辆实时仿真系统,并对仿真系统的准确性进行试验验证。综合应用等价类、边界值和分类树方法设计虚拟现实场景和测试工况,并应用于ACC和LDW测试。该系统不仅能够给驾驶员提供逼真的场景感受,实现驾驶员在环测试。还能实现车载控制器在环测试,对ADAS与现有车载控制器间的协同过程进行测试验证。
Considering the characteristics and test problems of ADAS,virtual reality and real time simulation technologies are employed in this paper to improve the test efficiency and find problems earlier.A vehicle real time simulation system was set up based on NI PXI platform and its accuracy was validated by experiments.The virtual reality scenes and test conditions are derived by combining the methods of equivalent class,boundary value and classification tree.The designed virtual test system has been applied to ACC and LDW. Tests was done with both driver and onboard ECUs in loop.The results shows that it gives realistic feel to driver and the cooperation between ADAS and onboard ECUs can also be validated.
